The Mechanical Heat Meter YG-RLM(D)-15-25 is a device used to measure the heat energy consumed or generated by a heating or cooling system. It consists of a flow sensor, temperature sensors, and a calculator that calculates the heat energy based on the flow rate and temperature difference.

The "YG" in the name of the heat meter refers to the manufacturer, Yonggang, while "RLM" indicates that it is a mechanical heat meter. The "D" in the model number refers to the display, which is a digital display. The numbers "15-25" refer to the size of the heat meter, indicating that it is designed to handle flow rates between 1.5 and 2.5 cubic meters per hour.

Mechanical heat meters have several advantages over other types of heat meters, including:

Accuracy: Mechanical heat meters are highly accurate and reliable, and can measure heat consumption with a high degree of precision. They can also handle a wide range of flow rates and temperatures.

Longevity: Mechanical heat meters have a long lifespan and can operate for many years with little maintenance.

Cost-effective: Mechanical heat meters are generally less expensive than other types of heat meters, making them a cost-effective option for many applications.

Simple installation: Mechanical heat meters are easy to install and require minimal plumbing modifications, which reduces installation time and costs.

No power source needed: Mechanical heat meters do not require an external power source, as they operate using the natural flow of water and the heat generated by the system.

Low maintenance: Mechanical heat meters are simple in design and require minimal maintenance, which reduces maintenance costs and downtime.

Compatibility: Mechanical heat meters are compatible with a wide range of heating systems, including district heating systems, heat pumps, and renewable energy systems.
